Title: Tape Library with rear magazine pullout mechanism
Inventor: WADA SATOSHI
IPC: G11B15/68
Filed: 2009-10-26
Abstract: Magnetic tape library device 10 includes: a front magazine (21) and a rear magazine 22 for housing a large number of magnetic tape cartridges (14); a device main body 11 in which the both magazines are housed in a parallel state in a freely slidable manner; an accessor mechanism 12 for transporting the cartridge taken out from the magazines; and a magnetic tape drive which loads the magnetic tape cartridge and reads/writes data. A magazine pullout mechanism 25 for pulling out the rear magazine and a magazine extracting mechanism 38 for extracting the rear magazine from the device main body are provided. The extracting mechanism may have a jet out prevention means 34 for preventing the rear magazine from being jetted out from the main body when the magazine is pulled out using the grasping member 27. Having rear and front magazines reduces weight and makes it easier to pull out and extract the magazines compared to a single piece magazine.

Title: Improvements relating to regulators for battery-charging dynamos
IPC: H02J7/22
Filed: 1947-04-17
Abstract: 624,043. Charging batteries; automatic control of current. LUCAS, Ltd., J., and LAIRD, J. A. April 17, 1947, No. 10192. [Class 38.(iv)] An excitation control circuit for a vehicle or other dynamo 1 charging a battery 3 comprises. normally closed contacts 7 in the field circuit 2 of the dynamo which contacts become vibratory under the action of winding 4 of an electromagnet 4, 5 in the charging circuit when the charging current reaches a predetermined value, thus limiting the charging current. The winding 5 is normally short-circuited by further contacts 8 of a relay 8, 9, the winding of which is energized from the dynamo or battery, so that at a predetermined state of charge the short-circuit on winding 5 is removed. This winding then assists winding 4 and causes vibratory action of contacts 7 at a lower charging rate and thus prevents over-charging. A further winding 10, carrying the charging current when contacts 8 open, may act on these contacts to maintain them open. A winding 11 responsive to the generator voltage may open the contacts 7 under excessive voltage condition, for instance if the battery becomes open-circuited. The charging circuit includes the usual cut-out 6. A lighting load 12 may be connected as shown, or directly across the battery.

Abstract: 1494962 Heat treating finely divided solutions VEITSCHER MAGNESITWERKE-ACTIENGESELLSCHAFT 12 March 1975 [25 March 1974] 10332/75 Heading C1A [Also in Divisions F4 and B1] A kiln 1 has burners 3 to produce upwardly streaming hot gases for heat treating finely divided solutions, e.g. aqueous solutions of MgCl 2  or other thermally decomposable metal salt supplied from spray nozzles 2. The major portion of the product oxide, e.g. MgO, falls into the bottom 6 and is removed by conveyer 7, while the fumes from the burner flames and reaction gases resulting from the heat treatment, e.g. HCl is removed at the head 5 of the kiln. These gases contain some material that has been incompletely calcined or decomposed and this material is separated in cyclone 8 and fed via a gate 10 to a flame tube 15 which is heated by an auxiliary burner 16 to a temperature in the range prevailing in the kiln chamber. Material is conveyed through the flame tube 15 by the hot gases and is calcined or roasted on its way back to the kiln chamber. Returned material is thus subjected to the equivalent treatment to that in the kiln and the mixture removed from the kiln will be uniformly treated.
